摘要： Optical slab waveguides are used as high-speed, high-capacity interconnects for parallel or other devices. Optical slab interconnects can connect to many more elements than can conventional electrical or fiber optic buses. A multiplexing scheme called “mode division multiplexing” greatly increases the number of independent channels that a single slab can support. Optical slab waveguides have a potential capacity of over one million independent channels, each channel operating at 1 GHz in a single physical medium, with each channel capable of receiving input from over 1000 ports and sustaining a load of over 1000.

摘要： Optical Packet Switching (OPS) is considered the most desirable switching technology for the ubiquitous optical networks that carry internet traffic. OPS could provide for great flexibility, capacity, efficiency, and bandwidth utilization that current switching strategies are not capable of providing. Despite its great appeal, OPS has been hampered by some major hurdles that prevented its practical implementation. Among such hurdles are optical buffering, optical processing/update of headers and to a lesser extent synchronization. This document introduces a novel technique for implementing packet switching in the optical domain. The new approach makes it possible to find efficient and cost effective solutions to the major problems that traditionally rendered optical packet switching (OPS) impractical. The new approach is applicable to any network topology. A complete suite of solutions to all aspects of optical packet switching that take full advantage of the basic novel approach are described. We present a complete set of solutions to the issues of buffering, header processing/update, regeneration, and synchronization among others. The new approach and affiliated solutions make it possible to implement OPS directly over WDM thus offering a very flexible optical layer capable of meeting future demand in a cost effective way.

摘要： A system is disclosed for implementing WDM optical networks, without blocking, and without the need for wavelength converters. The method is based on a hypercube topology for connecting the nodes, and a novel algorithm for constructing a routing tree such that blocking cannot occur even under the stringent requirement of all-to-all broadcasting. The algorithm uses shortest paths and a small number of wavelengths to satisfy the all-to-all connectivity requirement. The number of wavelengths used may, in fact, be the minimum number needed to satisfy the all-to-all connectivity requirement, using shortest paths.
